3 Claims. 1

The present invention relates generally to tie devices. More particularly the inventionrelates to that type of tie device which is adapted for use in tying together and holding against separation laterally spaced upstanding forms for "concrete walls or like structures and as its principal component parts comprises: (1) a combined tie and spreader rod which extends horizontally between the two forms and has one end thereof anchored to one of the forms and its other end provided with a loop at its extremity and arranged so that it extends through a hole in the other form and is disposed adjacent a single reenforcing beam such as a stud or wale on the outer face of said other form; (2) a bracket which fits against the reenforcing beam; and (3) a wedge which is slidably mounted on the bracket, is adapted to extend through the loop on the extremity of said other end of the combined tie and spreader rod, and serves when in place to connect the bracket to the rod and thus maintain said other form in its proper or desired position with respect to the one form.

One object ofthe invention is to provide a tie device'of this type whichisan improvement upon, and has certain advantages over, previously designed devices for the same purpose andis characterized by simplicity of. design, cheapness of construction and facility of? assembly and dismantlement.

Another object of theinventlon is to provide a tie device of the type under consideration in which the rod has a smooth cylindrical contour directly inwards of the point where it passes through the hole in the form with the reenforcing beam, the loop at the extremity of the end of the rod that extends through said form with the reenforcing beam is closedor complete and the bracket and wedge are so clesigned and constructed that when the wedge is in place they are locked against longitudinal displacementin either direction relatively to the combined tie and spreader rod.

A further object or the invention is to provide:

a tie device of the type and character under consideration in which the loop equipped and of the combined tie and spreader rod extends through a transverse aperture in the reenforcing beam and the bracket and wedge are so constructed and arranged that when the wedge is in its operative position wherein it extends through the loop no forces are setup tending to roll or rock the reenforcing beam relatively to the adjacent form.

A still further object of the invention is it; provide a tie device which is generally of new and 2 improved construction and efiectively 'anld efliciently fulfills its intended purpose.

Other objects of the invention and. the various advantages and characteristics: of the presenttie device will be apparent from a consideration of the following detailed: description.

The invention consists in the several novel features which are hereinafter set forth and are more particularly defined by claims at the conclusion hereof.

Figure dis a vertical section taken on-theline 6-4501? Figure 5 and illustrating in detail the manner in which the wedge coacts with the loop and the bracket so as to lock the bracket against longitudinal displacement in either direction relatively to the combined tie and spreader rod.

The tie device which is shown in the drawings constitutes the preferred form or embodiment of the invention It is adapted for use in connection with a pair of upstanding wall forming forms E and F and comprises a combined tie: and spreader rod I, a bracket 8 and a wedge St The forms are disposed in laterally spaced relation and are adapted to have concreteipoured therebetween for wall forming purposes. As weli understood in the art, the-forms are removed after hardening or setting of the: concrete. The form F comprises a comparatively thin flat1composite wooden panel 1 and an exteriorlydispose'd wooden reenforcing beam 1 in the iormof a stud or wale. Such beam extends horizontally, as shown in Figure 1. It serves not only to re enforce the panel I but also to align the planksthereofand is suitably secured by nails or other attaching devices (not shown) to the outer face of said. panel 1'. v

The combined tie and spreader rod 1 extends horizontally between the two forms F and F and is circular in cross section. It is disposed at right angles to the forms and has one end thereof extending through the form F and anchored to the latter in any suitable manner. The other end of the rod extends through a hole I in the panel 1 and a horizontal transversely extending aperture 1' in the reenforcing beam T The outer extremity of the-end of the combined tie and spreader rod 7 that projects through the aforementioned hole and aperture projects a comparatively small distance beyond the outer face of the reenforcing beam and is bent or shaped to form a loop Ill. The end of the loop is welded as at i l to the adjacent portion of the rod in order that the loop is .complete or fully closed. The aperture f in the reenforcing beam f is in alignment or registering relation with the hole I in the panel f. The aperture and hole are of sufiicient width to permit the closed loop IE to pass therethrough in connection with assembly of the combined tie andspreaderrod I: with respect to the form F. The portion of the rod that is directly inwards of the-hole f in the panel f has a smooth cylindrical contour and possesses no enlargement, washer or crosspin in abutment with the inner face of the panel 1.

The bracket 8 is in the'form of azplate metal stamping and fits against the outer face of the reenforcing beam F. It is horizontally elongated and consists of a flat intermediate wall l2 and a pair of vertically spaced horizontally extending sidewalls 13 and IA. The intermediate wall I2 fits flatly against the outer face of the. reenforcing beam f and is fixedly secured in place by Way of a pair of lag screws H5. The threaded shanks of the latter extend through horizontally elongated slots IS in the ends of the intermediate wall I 2 and project into the outer portion of K the reenforcing beam. The central portion of the intermediate wall I 2 of the bracket is provided with a horizontally elongated slot ll which is in registry with the outer end of the transverse aperture f in the reenforcing beam f and has the loop H! of the rod 1 projecting therethrough. When the device is assembled the loop ill, as shown in Figures 1, and 6, is disposed horizontally and projects through and outwards of the horizontal slot I! in the central portion of the intermediate wall I2 of the bracket. The bracket side wall 13 is formed integrally with, and projects outwards from, the upper margin of the intermediate Wall 12 and the bracket side wall 14 is formed integrally with, and projects outwards from, the lower margin of said intermediate wall. The (central portion of the side wall 13 is provided with a slot I8 and this extends at right angles to the intermediate wall l2 and is vertically aligned with the central portion of the loop receiving slot I! in the intermediate wall. The central portion of the side wall M of the bracket is provided with a slot l9 and this extends parallel to, and is in vertical alignment with, the slot H8 in the central portion of the side wall It. As best shown in Figure 2, the inner ends of the slots I8 and I9 terminate adjacent the outer face of the intermediate wall 12 of the bracket.

The wedge 9 is stamped from fiat plate metal and is mounted for vertical sliding movement in the slots l8 and I9. It is preferably arranged so that the small end thereof projects downwards. The slots [8 and I9 are of such length that when the wedge 9 is driven downwards the upper end of the wedge fits snugly in the slot I8 and the lower end of the wedge fits snugly in the slot IS. The central portion of the wedge is adapted to extend through the loop It! on the end of the combined tie and spreader rod that projects through the panel and reenforcing beam constituting the form F and is so dimensioned or proportioned that when the wedge is driven downwards into its operative position it fits snugly in the loop it. When the wedge is in place the bracket and wedge are locked against longitudinal displacement in either direction relatively to the combined tie and spreader rod and hence they, together with the rod, hold the form F in fixed spaced relation with the form F By reason of the fact that the loop equipped end of the rod 7 extends through the transversely disposed aperture f in the reenforcing beam f the forces which result from driving of the wedge 9 into its operative position do not tend to roll or rock the beam relatively to the panel f. When it is desired to remove the form F the wedge 9 is driven upwards until it is disengaged-from the loop I9. In order to maintain the wedge in slidably connected relation with the upper side wall of the bracket, i. e., the side wall l3, the lower end of the wedge is provided with acrosspin 2s. The length of this pin is slightly greater than the width of the slot I8 with the result that the wedge is permanently retained in connected relation with the upper side wall l3. The width of the slot l9 and the width of the space within the loop in are such that the pin is free to pass through said slot l9 and the loop when the wedge is shifted upwards in connection with release thereof from the loop.

When it is desired to use the tie device the form F is first erected or properly positioned and the adjacent end of the combined tie and spreader rod 1 is anchored thereto. Thereafter the form F is positioned in opposed relation with the form F and is manipulated so as to position the hole f in the panel f in registry with the loop I t of the rod 5. After such manipulation of the form F such form is shifted bodily towards the form F until the loop H3 is disposed directly outwards of the horizontal slot ll in the central portion of the intermediate wall [2 of the bracket. In connection with inward shift of the form F the wedge 9 is held so that the small or lower end thereof is above the slot ll, After proper positioning of the form F the wedge 9 is driven downwards so as to bring the central portion thereof into seated relation with the loop I0 and its lower end in seated relation with the slot IS! in the lower side wall M of the bracket. As heretofore'pointed out, when the wedge is driven into its operative position the upper portion thereof fits snugly in the slot l8, the central portion fits snugly in the loop lb, and the lower end fits snugly in the slot l9. When the device is fully assembled the form F is locked or held against longitudinal displacement in either direction relatively to the combined tie and spreader rod 7. After assembly of the device concrete is poured into the space between the two forms. After hardening or setting of the concrete the forms are removed from the concrete formed wall. In connection with removal of the form F the wedge 9 is driven upwards until it is disengaged from the loop Hi. Thereafter the form F is shifted laterally away from the wall. After removal of the form F the end portion of the rod T-having the loop Ill is severed efficiently fulfills its intended purpose and may be assembled and dismantled with facility. It is essentially simple in design and construction and hence may be manufactured at a low and reasonable cost. By reason of the fact that the loop at the end of the rod is closed or complete and the wedge, when it is in its operative position, fits snugly in the loop and the bracket there can be no slippage whatsoever of the form F with respect to the rod. The device is adapted or designed to be used with like devices in holding the two forms against separation during a concrete pouring operation. Whereas the device has been described as comprising a single bracket and a single wedge at one end of the combined tie and spreader rod it is to be understood that in practice the other end of the rod may be connected to the form F by providing said other end of the rod with a closed loop and utilizing in connection with such loop another bracket and another wedge, as shown in Figures 1 and 5. It is also to be understood that the invention is not to be restricted to the details set forth since these may be modified within the scope of the appended claims without departing from the spirit and scope of the invention.
